This invention relates to new and useful improvements in skates and has particular relation to skates of the type mounted upon wheels or rollers.

5 The particular object of the invention is to provide a skate as set forth havin .novel features of construction permittingt e. person skatin thereon to describe curves of substantia y small radii thus enabling the 0 person to execute fancy figures. I

Another object of the invention is to provide a-skate as set forth having novel features of construction permitting the pivoting of the forward rollers of the skate with respect to the skate proper.

Another object of the invention s to provide a skate as described having novel means limiting the arc of pivot of the forward wheels at a plurality of predetermined Another object of the invention is to provide a skate as described having novel suspension means for the rear wheels thereof effecting a relatively flexible connection between the wheels and body of the skate.

Another object of the invention is to provide a skate as set forthhavin means for v preventing the pivoting of the front wheels of the skate.

Another object of the invention is to provide a skate as described having means at the rear end thereof for the purpose of preventing said skate from sliding from under the person skating thereon.

Other features and details of construction are set forth hereinafter and disclosed in the accompanying drawings, in which:

Figure 1 is a view in plain elevation of a skate embodying the invention;

Fig. 2 is a view in side elevation of the disclosure in Fig. 1; I

Fig. 3 is a view in longitudinal section on line 33, Fig. 1;

Fig. 4 is a detached View in section on line 44, Fig. 3; 1

Fig. 5 is a detached View in section on line 5-5, Fig. 3; and

Fi 6 is a detached view in erspective of the ront wheel bracket and t e adjustable means restricting the pivoting of said bracket within predetermined limits- Heretofore, fancy figure skating for the most part has been restricted to ice skates and roller skates having but two alinged wheels or rollers. By this invention I provide a roller skate of the ordinary our wheel or roller variety having novel construction, enabling the person skating-thereon to describe (fancy figures as in ice skating, and execute within a substan-- turns and other courses tially small radius.

Referring now more particularly to-the drawings, a skate made in accordance with this invention comprises front and rear top plates 1 and 2 respectively. In the present instance, the front plate 1 is provided with I the, customary shoe cleat elements 3 adjacent each side thereof which may be adjusted by means of the threaded element 4, to meet the needs of the particular skater. The rear top plate 2 is provided with the customary back plate 5. v

The aforementioned top plates 1 and 2 are mounted upon longitudinal channel members 7 and 8 respectively. The forward portion of the channel 7 comprises a circular bearing plate-23 disposed at an angle with respect to the top plate 1 the purpose for which will be set forth in detail hereinafter. The channel '8 is similarly provided with depending lugs 9 and 9a which are formed integral therewith with the said lugs being provided with apertures therein for the assage of a pivot pin 10. vA channel mem er 11 is mounted internally of the channel members 7 and 8- and adj ustably secured to each of said chan-;

nels to permit the length of the skate to be varied at the discretion of the skater.

The rear wheels 12 are rotatably mounted upon a shaft or axle 13 which is in turn mounted-in the side walls 14 of a bracket 15. The bracket 15 is further-provided with upstanding lugs -16 and 16a at the front and rear thereof, the said lugs havin apertures therein for the passage of the pivot pin-1O therethrough, constituting a bearing about which the bracket 15 may pivot, thus affording greater flexibility between the wheels 12 and the skate body.

; adjacent the rear extremity thereof, and

operates against the action of a spring 19 which embraces said pin 10. A roller 20. is rigidly mounted at the lower extremity of the bar 18 and is positioned to just clear the floor or surface on which the skate rests. An

. arm 21 extends forwardly from the bar 18 and is provided with a curved portion or hook 22 at the forward end thereof which is arranged to engage the axle 13 and limit the rearward movement of the bar 18, which occurs when the roller 20 contacts with the floor or other surface, to prevent the skate from slipping from beneath the person skating thereon.

The forward channel member 11 is provided with a rearwardly inclined bearing late 23 having an upstanding lug 24 at the orward end thereof, and a centrally disposed aperture 25 for the passage of a pivot bolt 26. The forward rollers 27 are mounted on an axle 28 which is supported in the depending extensions 29, 29 of a bracket 30, the said bracket 30 being disposed substantially parallel to the plate or disk 23.

For the purpose of providing relatively friction free turning of the bracket 30 with respect to the bearing, plate 23, it has been found desirable to dispose a plate or disk 31 intermediate the bracket 30 and plate 23, the.

said plate 31 having suitable openings there- 1n, arranged for the reception of roller bearing elements 32 which contact in the present instance with the aforementioned racket 30 and bearing plate 23, the plate 31 functioning primarily as a means for maintaining the rollerbearings in operative relation with the surfaces of the bracket and the bearing plate. The bracket 30 and the disk 31 are each provided with a center opening for the passage of the pivot bolt 26.

A spring 33 having'arms 34 and 35 respectively, embraces the pivot pin 26 adjacent the upper extremity thereof, the forward arms 34; and 35 being arranged to reside in the notches formed in the aforementioned lug 24 and the lug 36 on the front of the bracket 30. The spring 33 functions to yieldingly maintain the bracket 30, and the wheels 27 carried thereby, in normal position, and yet permit the pivoting of the plate 30 about the pin 26 in a direction and degree, depending upon the location and amount of pressure applied to the skate by the skater. r

A stop 37 projects upwardly from the rear of the bracket 30 and operates to limit the turning movement of the bracket 30 by endegree of turn of the bracket 30 may be restricted within predetermined limits by advancing the channel 38 so that one of the formed steps thereof lies in the path of the stop 37 on the bracket 30. The innermost notch in the channel 38 is of sufiiciently narrow width that the bracket 30 will be locked against turning when the notch is engaged by the stop 37. The upper edges of the flanges of the channel 38 are each provided with a raised knob 42 arranged for engagement with a series of recesses 43 in the under surface of the plate 44, the said knobs and recesses being suitably positioned so that upon engagement of corres onding recesses by the knobs a predetermined step 41 will lie in the path of the stop 37 on the bracket 30.

By the arrangement of the bearing plate 23 and the. bracket 30 at an angle with respect to the top plate 1, the moment the skater applies pressure to the right or left side of the skate, the bracket 30 will pivot on the roller bearings 32 thus placing thewheels 27 at an angle, the wheels remaining in the turned p0- sitlononly so long as the pressure is applied and when the pressure ceases or is lessene the spring 33 will return the bracket 30 and wheels 27 to the normal position or positions corresponding to the degree of pressure still existing. I

In using the skate which is the subject of this invention, the skater may describe fancy figures and other courses that have heretofore been impossiblewith the customary type of roller skate. The skate herein described is of substantially rugged construction and provides a skate that is desirable to the public.

While one embodiment of the'invention has been set forth for purposes of description, it is not intended to be restricted thereto except as set forth in the appended claims.
